压缩Vue.js打包后的体积方法总结(Vue.js打包后体积过大问题)

app.js    2.3MB
vendor.js   2.4MB
vendor.css  612kB
app.js.map  9.13MB
vendor.js.map 16.21MB
//不一一列举....

new webpack.optimize.UglifyJsPlugin({
  compress: {
    warnings: false
  },
  // sourceMap: true //将sourceMap关闭就不会打包出.map文件
}),

Vue.use(Router)
export default new Router({
  routes:[{
    path:"/",
    component:function(resolve){
      require(["./../components/Index"],resolve)
    }
  }]
})

const Foo = () => import("/Foo.vue)
``` 

Vue.use(Router)
export default new Router({
routes:[{
path:”/“,
component:Foo
}]
})

module.exports = {
  entry:{...},
  output:{...},
  resolve:{...},
  module:{...},
  externals:{
    "echarts":"echarts" //不打包的包名
  }
}
